SPECIFICATION forming part of Letters Patent No. 605,930, dated June 21,1898. Application led September 2l, 1897- Seral N0. 5521425. (No model.)

.To all whom t may concern: .l

Be it known that I, JOHN H. STAUFFER, re-

A siding at Gap, in the county of Lancaster and State of Pennsylvania,have invented 'a new and useful Vire-Picket-Twisting Machine, of whichthe following is a specification.

My invention is in the. nature of a device for twisting wire to form itinto pickets for wire-picket fences.

The object of my invention is to furnish a simple, durable, andeffective machine whereby any one without previous practice orknowledgewill be enabled to accurately and rapidly form twisted wire pickets witha loop in one end and the other end forked ready to be applied to afence.

With this obj ect in view my invention consists in a device or machinefor twisting wire pickets, comprising a base having a rigid head at oneend and an'iadjus'table head at the other end, the adjustable head beingprovided with a hook over which to bend the Wire and the fixed headbeing provided with a journaled shaft carrying a clamp to grasp the twoends of the wire, and a crank or handle whereby the shaft may be turnedand the wire 4twisted and formed into a picket, as before described.

My invention further consists in the improved construction, arrangement,a'nd combination of parts hereinafter fully described, and afterwardspecifically pointed out in the claims.

In order to enable others skilled inthe art to which my invention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation, having reference to theaccompanying drawings, forming part of this specification, in whichlFigure 1 is a perspective view illustrating my invention in position forpractical use, showing the wire engaged therein prior to twisting and atwisted wire picket alongside.

Fig. 2 is atop plan view of the device as shown in Fig. 1. Fig. 3 is acentral vertical longitudinal section through the same. Fig. 4 is adetail perspective view illustrating the various parts of my devicedetached from each other.

Like letters of reference mark the same parts wherever they occur in thevarious figuresl of v the drawings.

1 Referring'to the drawings by letters, A is the base 'ofthe machine ordevice, upon one end of which is@ mounted the fixed head B,

while the other end is slotted at C and is provided with a head D,attached by means of bolts E, passing downward through the head andthrough the slot C and secured on the lower side of the base bymeans ofsuitable nuts. These bolts are, before passing through the bolt itself,passed through a hook F, so that when the head D is adjusted and securedin position the hook F is rigidly secured to the head. The head B has alongitudinal groove G on its upper side, about semicircular incross-section, in which a shaft II is laid and which is secured thereinbya clamp-plate I, which Vforms the upper half of a bearing in which theshaft II may rotate.

The shaft H is provided on its outer end with a crank or handle J, bymeans of which it may be turned, and on its inner end with a plate K,having a central opening L therein. M is another plate of the samedimensions as the plate K and which is provided with a verticalscrew-threaded stem N, adapted to pass through the central opening L inthe plate K and receive a thumb-nut O for the purpose of securing thetwo plates together.

To operate my invention, 'a piece of wire P is passed over the hook Fand bent at its middle point therein, its two ends being brought backand clamped between the plates K and M.y The shaft Il is then drawnoutward until the wire is properly stretched, when it is secured againstslipping back by clamping a ring Q around it at the outer end of itsbearing. p twisted to any degree of tightness desired, the result beinga wire picket, as shown at R in Fig.' 1, provided with a loop S at oneend and forked at Tat the other end.

From the foregoing description it will be obvious that I have provided asimple, cheap, and durable device for the purpose intended, which ismade of but a fewinexpensive parts and so constructed as tobe but littleliable to wear or breakage with ordinary usage.

Vhile I have illustrated and described the best means now known to mefor carrying out The shaft is now turned and the wireV IOO inyinvention, I do not Wish to be understood as restricting myself to theexact details of construction shown and described, but hold that anyslight changes or variations, such as niight suggest themselves to theordinary inechanic, will properly fall Within the limit and scope of niyinvention.

Having thus described 1ny invention, Wha I claim as new, and desire tosecure by Letters Patent of the United States, is

l. In a Wire-pieket-twistin g device, the conibination of a baseprovided with a fixed head at one end and alongitudinal slot at theother, an adjustable head and a hook thereon mounted over said slot,bolts passing through the hook, the head and the slot and secured on theunder side of the base by nuts, a longitudinal shaft journaled in thefixed head7 a clamp secured upon the inner end of the shaft, and meansfor turningthe shaft, substantially as described.

2. In aWire-pieket-twistingdeviee,the coinbination of a base providedwith a fixed head at one end and a head and hook adjustablelongitudinally of the base at the other end, a longitudinal shaft seatedin a seniieircular groove in the fixed head, a elampingplate providedwith a seniieircular groove secured to the fixed head and forming theupper half of the shaft-bearing, a plate secured upon the inner end ofthe shaft and provided with a central opening, a second plate parallelWith the shaft-plate having a screw-threaded stein to pass through theopening in the shaft-plate, a thumb-nut engaging the screw-threadedstern to draw the two plates together, a cla1nping-ring to prevent theshaft from bein g drawn inward, and a handle for turning the shaft,substantially as described.

3. In a Wire-picket-twistin g device,the conibination of a base providedwith a fixed head at one end and a longitudinal slot at the other7 anadjustable head and a hook thereon 1nounted over said slot, boltspassing through the hook, the head, and the slot and secured on theunder side of the base by nuts, a longitudinal shaft seated in asernicircular groove in the fixed head, a clamping-plate provided with asemicircular groove secured to the,`

fixed head and forming the upper half of the shaft-bearing, a platesecured upon the inner end of the shaft and provided With a centralopening, a second plate parallel with the shaftplate having ascrew-threaded stem to pass through the opening in the shaftplate, athumb-nut engaging the screw-threaded stein to draw the two platestogether, a clamping ring to prevent the shaft from being drawn inward,and a handle for turning the shaft, substantially as described.
